There will be 6 clinic visits during your pregnancy, involving several assessments. As much as possible, we will try to schedule these clinic visits on the same day as your usual antenatal visits. Abdominal ultrasound scans will be studied to measure your baby’s growth and development. Oral glucose tolerance tests (OGTT) will be done and blood will be collected to be measured. Your body measurements, eye check, blood pressure and cardiovascular function will be assessed, and a trained interviewer will ask you various questions about diet, medical history, behavioural factors as well as lifestyle factors before and during pregnancy such as smoking and physical activity.
